When I first clocked this - it immediately brought to mind my recently acquired AC Noises Ricorda Granualar Reverb, amd while there is some degree of overlap between the two - each device is also very distinctive in its own way. Where the QI Etherealizer adds Chorus, and Parallel as well as Series Routing.

 

It’s a device that perfectly covers Yvette’s key tones in the one device.

 

Controls - MIX } Mix / Dry (Series / Parallel), Grain, Delay, Chorus; MAIN } Mix / Dry (Series / Parallel), Tone (Resonant LPF), Space (Hall Reverb), Flow (Routing) : Series / Parallel, Bypass Footswitch (Bypass + Freeze Fsw = Preset); GRAINS } Grain Mix, X (Grains Interval / Density), Playback : x1 / x2 / x.5 / Reverse / Random, Grain Mode : Grain Cloud / Phrase Sample, Freeze Footswitch; DELAY } Delay Mix, Delay Time, Feedback, Delay Divisions : Quarter / Dotted Eighth / Eighth; CHORUS } Chorus Mix, Rate, Depth, Chorus Mode : Tri / Stereo, TAP/OSC Fooswitch.

 

Rear Ports : MIDI In, MIDI Thru, USB-C, 9V DC [-] 300mA, In Mono (L), In Stereo (R), Out Mono (L), Out Stereo (R).

 

I’ve often said that format matters to me, and were I to acquire the QI Etherealizer - it would likely be on the current Strymon BigSky MX slot - which is a fairly significant pedal for me. I was able to fit the AC Noises Ricorda onto a different much smaller slot - that’s a much more flexible pedal for me in how it fits within my rig.

 

I really like this device - I guess it could also step in on the Hologram Microcosm slot. While I can mostly recreate the sounds of the QI with pedals already in my chain - albeit I would need something extra to get those 4 effects in parallel! So it’s definitely a very unique device!

 

At $449 it’s a fairly significant investment, but considering everything that’s onboard this device - it’s probably a very fair price. The QI Etherealizer is up for pre-orders currently on most dealer sites, and you can read up more on this device on the Walrus Audio Website.
